(NYDAILYNEWS) — Two middle school bullies have issued lukewarm apologies to the 68-year-old school bus monitor who they tormented, threatened and ultimately drove to tears.

Appearing on Anderson Cooper’s show Thursday night, Karen Klein, a bus monitor in upstate New York, spoke about the verbal abuse she endured when a group of students from Athena Middle School targeted her on the bus ride home Monday afternoon, then uploaded video of the cruel harassment to the Internet.

Cooper revealed two of the four students had issued statements of apology.

“I am so sorry for the way I treated you,” one of the students, named Josh, said in a statement. “When I saw the video I was disgusted and could not believe I did that.”

But Klein says she’s hesitant to believe the student is sincere.
